Potential limitations with the Endotrol

1. Potential limitations with the Endotrol • (i) its use during videolaryngoscopy-assisted intubation is not well defined • (ii) furthermore, it was designed specifically for nasotracheal intubation because it is made of softer plastic than is a standard tube, which can limit its use when a rigid device is required • (iii) its use in procedures using laser or electrosurgical active electrode in the immediate area of the device is contraindicated.

3. As with airway protection, eye protection is a consideration in cases involving sedation and local anesthesia only, such as in dentistry. • An intermediate eye-protection alternative to consider, both in terms of cost and convenience, is the use of a surgical mask.

4. Instead of placing the mask and its malleable metal nasal contour strip over the nose to cover the mouth, the mask is inverted and the contour strip margin becomes the inferior border allowing coverage of the eyes. • Masks with elastic ear loops appear to be the most convenient style for this technique. • When using general anesthesia, taping the lids with concomitant use of globe lubricant as needed and surgical towels is often the optimal option.
